Let's figure out how to convert internal MXM connector an external PCI-E x16 box

Hello ShadowsNight! I want to connect the external video card to the notebook via the mxm connector. I can buy from you an adapter with mxm in pci-e ? How much is it?

 

Is there a way to trick motherboard into thinking there is a graphics card installed in the mxm slot?

Asking for a different project

 

I doubt it, why does the slot need to be empty?

 

Trying to run a laptop without a graphics card installed, but the embedded controller turns it off after 30 seconds.

 

Oh I see, I'm guessing this is a clevo unit? I think you're not going to have a choice but to buy a card that is compatible I know taobao rx 480s won't satisfy the EC of those systems

 

Yeah I'm pretty sure it tells there is a GPU there via the SMBus, with the alienware bios at least, since it can tell that it's an AMD or Nvidia chip, you could try shorting the PRSNT_R# (Pin 2) and PRSNT_L# (Pin 281) to ground though (for a MXM 3.0 slot). It won't hurt anything unless you get the wrong pins.

 

Hello ! I am writing to you from Russia. Please help with mxm to pci-e adapter. I want to put a video card from a laptop in my PC. All old links to files have already been lost. And because of the miners in our country, there is a large deficit with video cards

 

I've actually wondered the benefits of using MXM cards for mining, they would be better power to performance at any rate. But, the problem is that your probably still better getting a desktop card, a 760GTX is 2x as fast as a 780m so you would need to spend a fair bit on the MXM cards to get the same performance.

 

Dont bother using any MXM for mining, they are all still too expensive for it.

 

was more that I had a passing thought one time, I have 2 780m and one 770m lying around, and performance per watt seems to be the big thing these day's, personally haven't managed to start mining, something to do with the block chain, too hard basket atm I have my plate full already but I did run a bench mark with ethminer and got 10.5mh/s with the 780m when compared to my 17.3mh/s benchmark with the 780gtx in my desktop it's probably better on the power side of things, at least on paper (780m 100watt vs 780gtx 350watt).

But on the original off topic, topic there was PCI-e to MXM adaptors around, google shows lots of images but I'm not sure where to buy them anymore, I remember seeing some shady Chinese website at one point that was selling them for 60 usd. Sorry I can't be of any more help.

On another news I've almost drawn up the final MXM board, should be down hill from here

I managed to get x2 lanes running at 8gt/s for a little bit using 16 sata cables crimped in the 2x20 connectors, then I bumped it and it all went south, after that, I was going to go outside and start soldering up a board without the connectors and solder every wire to the boards but it's -1 outside here and I'm not allowed to solder in the house, I share the place and people get grumpy.

Edit: @ frol2000 try looking up HP Multi MXM probably more than your after but it's something that people are selling (at least to Australians) http://www.ebay.com/itm/HP-716553-001-MULTI-MXM-PCIe-WS460C-PROLIANT-Gen-8-713700-002-/272024112725

 

Has anyone got any recent progress updates regarding the "adaptor" I happen to be local in Australia if you could send out a spare board... I also, conveniently have an alien ware 17r1 that needs a GPU refresh. @ShadowsNight

 

I have to say this idea is great and if you need an Alienware M18 R3 to test then im down.
I also have a titan X sitting here that I could do some testing on.

 

You can easy upgrade your system with a new mxm gtx1070 gpu

-17 r1 with MSI Gtx 1070 http://forum.notebookreview.com/threads/msi-1070-in-alienware-17-r1-ranger-success.797893/

 

Will this method work on the Alienware 18 R1?

 

You need optimus or an edp panel for new pascal cards

 

I hope so, this is the whole reason I started this crazy crusade

This is probably the case, at least using your internal display, my current test laptop does not have a screen and works with and without Optimus enabled. I'm hoping to have my end product have the ability to have the display work plugged into the desktop GPU, but it's looking like it will end up as an accessory. Since the cost would be too high for a standard kit and most people have the option of Optimus and wont mind the small performance drop. and those that do have a problem can afford the accessory.

Good news I'm still moving house but I have a work space! I currently have Alienware M18x R1, M17x (not sure the revision, I can't remember and need to boot it to check, service tag has rubbed off), and 2 Alienware 17 R1's, I'm doing all my initial testing with the 17's because if I fry one I still have another. I'm still chasing stable pci-e speeds faster than 2.5gt/s, I've had 8gt/s with 4 lanes but it was unstable with the boards I was using.

Edit: On the production side, I've been talking to a company that makes enterprise cables and connectors, and it looks like it will cost me $4700 AUD to set up production with them plus the units, but they have the highest cable density with the guarantee of all x16 pci-e lanes at 8gt/s and will test the unit at the factory and give me the spec sheets of what they are capable of, might even be able to get pci-e 4.0 if they don't change the MXM port

 

If we were to use the adapter would we still need an external power supply? If you need a website to sell the adapter I would suggest banggood.com as they already sell mpcie to x16 docks that have been reviewed by a variety of people. Another question, how much would one of these adapters cost the consumer without gpu or power supply?

 

@ShadowsNight, do you have a list of pin pairings you're going off of that was successful?
I'm looking to do something similar but go the other way and it'd be great if I didn't have to start from the ground up

 

Alright since it seems like life doesn't want me to finish this project here are the pins I used XD

Looking at my notes (which are all rather sketchy) I used all the PEX pins and the SMB pins, shorting the ones that needed to be tied to ground.

I am not saying this will work, it's been a while since I've had the time for this project and my notes are very vague, and I may be missing some.... I guess I figured I'd remember it all.
